DCM1 & DCM1e Installation and User Guide v1.038

Set Key

SELECT INPUT

Set Key

1234

Numeric buttons enter key

This menu function enables the DCM1 Installer Mode key to

be changed from the factory default setting of 1234. Changing

the key from the default to one “less obvious” is strongly

recommended.

The key may be any 4-digit number, but comprised of digits 1

to 8 only.

Enter the new 4-digit key using the eight numeric buttons. No

additional actions are required for the new key to become

active.

UTILITY

The Installer Mode key may be changed from the

INSTALLER KEY tab. Enter the current key in the Old

Key eld, then enter the new key in both the New Key

and Repeat New Key elds. Click Send Key to

transmit the new setting.

The Installer or Power Keys may be changed from the

browser window by selecting Cong, then Change

PIN. Enter the current key in the Enter your

current PIN eld, then enter the new key in both

the Add a new PIN and Conrm your new PIN

elds. Click the Reset button to conrm the change. The

key changed will be that corresponding to the original

PIN entered.

NOTE: There may be occasions where it is necessary to

access Installer Mode to change the Installer key, without

knowing the current Installer key. This typically happens

some time after a system has been installed, when the

original installer is no longer available.

In this situation, turn the DCM1 off, remove the top

cover and move jumper J8 to its alternative position. (See

page 65 for details of jumper locations.) This forces the

Installer Key to the original factory default. Power the

DCM1 on, and enter Installer Mode, using the default key.

Set a new key in the Set Key menu function. Then go to

the Save Defaults menu function (see page 39) and

press the rotary control to save the current settings. Turn

the DCM1 off, replace J8 to its original position and ret

the top cover. On re-powering the DCM1, the new key

will be required to access Installer Mode.

RS232 Baud Rate

SELECT INPUT

Rotary Control sets Baud Rate

RS232 Baud Rate

9600

This menu function sets the data rate (baud rate) of the

DCM1’s RS-232 Control Port. If no external control system

or other equipment is connected to the RS-232 port, the

setting can be ignored.

Most control systems and other equipment using RS-232 are

able to operate with a wide range of baud rates. It may be

simpler to set the baud rate at the controller and leave the

DCM1’s setting at the default.

The default setting is 9600 baud (displayed as 9600). Use the

rotary control to change the setting. Alternative baud rates

are 300, 1200, 2400, 4800 and 19200. The baud rate applies to

both data transmit and receive.

The numeric buttons are not used in this function.

RS232 Flow

SELECT INPUT

Rotary Control sets RS232 flow option

RS232 Flow

No Flow

Some external equipment requires the RS-232 ports of devices

to which they are connected to be congured in a certain

way, particularly in regard to the way data ow between the

transmitting and receiving device is managed. The two most

common methods of data ow control are Xon/Xoff and

RTS/CTS, alternatively referred to as software control and

hardware control respectively.

The rotary control selects which of these control methods is

applied to the port. A third option, the default, is for no ow

control to be applied.

The numeric buttons are not used in this function.

Note that hardware ow control requires additional pins on

the RS-232 port to be connected. See page 66 for more

details.
